Abstract

A technique facilitates anchoring between tubular structures in various well applications. The technique may utilize a load anchor having a radially expandable mandrel with an interior passage. Circumferential biasing members are mounted around the mandrel and each circumferential biasing member has a biasing surface. Additionally, a gripper system is positioned axially between the circumferential biasing members. The gripper system is configured such that engagement with the biasing surface of either circumferential biasing member causes radially outward biasing of the gripper system upon movement of the mandrel in either axial direction. A sealing element also may be disposed about the mandrel. The configuration of the gripper system and the circumferential biasing members protects the sealing element against undue axial movement once the load anchor is radially expanded into engagement with a surrounding surface.
